We use 1.2 in distributed clusters with one-way failover. Primary master
listens to slaves results via NSCA, secondary (failover) master runs a
standalone nagios instance monitoring the primary master (nagios, nsca,
host, + anything else) using an event handler to process the failover.
During failover the secondary master rebuilds configs for itself and the
slaves, pushes these out and restarts remote and local instances.
